j Application June 29, 193s, serial No. 216,529 i claims. (ci. 299-141) This invention relates `to controlled aerated liquid delivery.

This invention has utility when incorporated in directionable, multi-jet concentrationV for massage-like invigorating and cleansing impact ,Y

as on the scalp of one receiving a shampoo.

Referring to the drawing: f

Hot water line i is shown as provided with valve 2 (Fig. 8). Adjacent thereto iscold water supply line 3 with valve il coactingrfor controlling the mixing temperature of the two water supplies in passing to common delivery duct 5, to

which maybe connected by bolts E clamp collar i (Fig. l) embracing terminus of rubber tube 8 as enveloped by wire helix 9. This helix 9', which is assembled about the distended tube 8, upon release of the tube provides a' protective armor effective to hold the duct even under pressure` against twisting or jumping with symmetrical uniform resistance' to iiexing in! all: directions, even to the arc to approximate abutting relation for theY wire of the helix. This rubber tube 8 has the wire if! `extend therealong in such proximity to opposite terminal taper fitting I (Fig. i). Complementary taper tting II having knurled rim I2 may have threads I3 between the nut tting I2 and' head portion I 4 effective not only'to clamp the flare terminus of the rub- ACII ber hose 8 but therewith a terminal portion of the helix 9. Accordingly, this helix 9 is not only held at the clamp I but at this tting I0, I2, and thereby anchors the hose positively as to this helix. i Y

The head portion I provides seat I for rubber seat Iii anchored by screw Il into guide stem i3 extending through perforate diaphragm or spider IS, thereby leaving annular series of openings 2t for liquid flow supplied under pressure from the hose il. In practice, this pressure may run say forty to eighty pounds per square -i-nch or even higher. From this head portion I4 eX- tendsflare 2l to annularly corrugated` closure disk 22 having on the convex outer portions 23 of the corrugations delivery ends ofgcylindrical ports 2d as in annular series providing high pressure jets for the liquid from chamber 25 in the nare portion 2 I.

Transversely across this chamber 25 extends sleeve sections 2t, 2l, in alignment with each other andv spaced to mount therebetween cam 28, having connection by key u2Q to shaft 30 through these aligned sleeves 26, 2l. Fixed to the termini of this shaft by screws 3 Iisnger or digit-operable bail 32, which is in position for convenient rocking either by the thumbor finger from closed position adjacent the flare housing ZI to slightly open position, say for cloud effect, or in degrees therefrom to fully open position against the head portion I, thereby so unseating4 the che-ck valve i6 that the pressure volume of water is effective for impacting jet flow action. The bail 32 is normally in check` valve closing position to seat against the headflare `2l However, to insure this direction of actionas well as steady the valve in opening swinging of" this bail 32,there is torsion spring 33 anchoring with the cam 2i? and the sleeve 2l fixed withlthe flare 2l. Centrally of this corrugated disk 22 isboss Sliwhich may engage seat 35Y in opposing Idisk 36 having spray limiting shield or shroud 3l as drawing inwardly therefrom.

Screws 3i? from this disk 35 engage the` boss 34 not only in assembling this disk 36` with the head section having the disk 22 but in such assembly bringing ports 39 into alignment with'the ports Eil. These ports 39 have lare entrance portions 'it at the ridge portions of corrugations :il in the disk :it as toward the corrugated disk 22. There is thus provided air chamber regions between these oppositely concave groove portions as annular for the opposing disks. This Vhousingflare 2l has clearance i2 as to the extension or shroud 3l. Accordingly, there is annular air areas 'tion -sudsing or lathering is promoted for its With this bail 32 slightly lifted, hair 54 of the patient receiving the shampoo may be moistened to the slight degree desired for effective subsequent lathering or Soaping or otherv cleansing treatment. As this massage or working of the cleansing substance or ingredient into the scalp may be effected, say by hand, such may be supplemented not only for the sudsing or lathering action but for the removal thereof according to thev degree of impinging eifect desired from `the multi-jet tool as distinguished by more open position in the swinging of the bail and the desired spacing of the delivery outlet t3 from the hair. This manipulation is readily elfected efficiently and rapidly for the initial setting of Vthe valves 2, 4, for control of the temperature may not be disturbed notwithstanding, after the administration of the cloud ofdampening, the

tool may be dropped aside, and it Will not leak 3()I because the check is automatically set and held. As the attendant or operator desires further attention, it is only necessary to grasp the tool head and with the digit effect the desired opening and shifting, even into dicultly accessible regions about the head of the one undergoing treatment. In practice, the individual may be so disposed that the head may hang over or in proximity to a bowl to receive the hair and moisture. No matter which portionrof the head of the individual is toward the bowl, this short range of flexing possible in the supply duct or hose 8 permits ready access without kinlnng or without hazard from rupture of the line or duct even though high pressure is used.

This pressure delivery of the impacting small cross-section streams into the scalp may ini- Vtially beanalogous to rubbing or massage action as further effective in these minute or shielded Due to the liquid flow and air associaeifective action Yin degreasing or removing oil vfrom the-scalp regions as well as other impurities to the extent desired. As this volume of liquid is continued there is a rinsing or Washing away of the soap and lather. According to the extent of treatment desired, there may be a resupply of the cleansing substance, say o f the order of soap or other scalp treatment which may Ybe for supplemental aeration and liquid course as Well as rinsing to follow. These manipulations may be in rapid succession with the initially xed temperature control as set by the valves 2, or a desired departure therefrom, sa-y even to a slightly cooling or refreshing iinal cleansing.

' `Theextent of air supplied to the scalp, to-

gether With the liquid and the force thereof, has" in practice been effective in so uffing or loosening up the hair that final drying is attained with much greater expedition. The extent of the air as thus impacted or blown into the hair and about the scalp has, in `addition to the lcomfort feeling of cleanliness, a refreshing effect,twhich response of the patient may be atf convenient shape for handling and giving a lotributed not only to the air itself but to the aerated liquid as of a more pleasant reaction value as well as more elective in its cooperation for completing the shampoo. This air commingling with the definite temperature control means that the shampoo operator may effect with much less Water a thorough lathering action, and like- Wise with reduced amount of Water a more quick, fully eifective, pleasant shampoo experience for the customer, with a saving of time to such eX- tent that the number of persons treated may be doubled with the resulting treatments much more desirable than in hand manipulation method or With ordinary duct supply and rosette type of spray.

In operation, even at slight turning on of the pressure for dampening the ratio of the ports or openings is such that the inner basis openings ll eifect such a concentrated iiow into the openings 39 that there is not spill at the annular clearance 42. With the tool held in upright position, say as the opening i3 is upward, this low rate of delivery may effect a filling of the chamber provided by the wall 3l, and then will ooZe over the sides to run down outside. As this pressure is increased, say to lift the water one-half inch or more above the opening 113 a few bubbles will seem to work through; and as this pressure is increased, the full charge of Water in the region surrounded by the Wall 3l is thrown Aout or evacuated. There is accordingly assurance from this mode of operation that With a delivery pressure in effective impacting, reduced pressure occurs in this shrouding wall as such is an aid in concentrating the delivery, Y

Furthermore, this shrouding or throat reduction has a tendency to reduce splattering or dispersion of the water away from the region sought The general spherical contour is in a cation for the mild action as close to the hair or scalp, while aswitlidrawn the inertia or the impact is seemingly more effective.

The aerated penetrating action from these impact jets is such an effective clearing action or rinsing that curds or objectionable residues as from soap or oil in the scalp are removed and this includes even alkali tendencies from the soap. There is thus enhanced the treating values tol be had from subsequent handling of the scalp and hair. For instance, inthe event of a dye or color treatment even 'to the henna action, this is effected in a uniform normal response throughout, for the hair and scalp are uniformly treated and cleansed by the shampoo tool as herein disclosed.

This rinsing or cleansing of the scalp is mechanically effective hereunder in the conduct of the shampoo with such a degree of thoroughness that even in -difcult treatments occasion does not arise for attacking the objectionable conditions, say from hard water or eXtreme diihculties arising therefrom, as to which effort to avoid may be approached by acids such as vinegar, lemon or chemicals. This means that the desired high state ofcleansing is mechanically effected in this shampoo without the chemical attacks, either basic or acid.
